Tuesday December 06, 2005 Check out our new Java performance tuning whitepaper on java.sun.com.
This has been on the Java performance group's to do list for very long time, thanks to Tom Marble for making this happen. There's nothing liking the kickin' performance the new UltraSPARC T1 processor, the Sun Fire T1000 and T2000 servers, and our latest update release J2SE 5.0_06 to give the needed kick in the pants to put out a tuning guide. This is a work in progress so your feedback is very much appreciated and needed. Thanks.
UltraSPARC T1 Screams Running Java
Sun has announced the new Sun Fire T1000 and T2000 servers today along with SPECjbb2005 benchmark results on these systems. What makes these results so special? They run the UltraSPARC T1 processor with 8 cores and 32 threads on a single chip. The performance of the UltraSPARC T1 systems easily surpasses performance on all other 1U, 2U, or 4U Systems. These results also leverage the high performance features in the newly released J2SE 5.0._06.
Take a look at the the chart below. The Sun T2000 surpasses all other competition in the 2U and 4U space. The 1U Sun Fire T1000 leads the 1U results.
How are these results comparable? Its simple, compare the raw throughput SPECjbb2005 bops score. One may ask: "How can you compare a 8 core / 32 thread box to a 4 core / 8 thread Power 5+?". Its easy. Chip and core counts are steadily becoming irrelavent. What really matters is how much work (throughput) a system can achieve, how much is that system going to cost to run, and how much lab space, power, and cooling will this system require. Looking at the above results with this in mind clearly shows why Sun UltraSPARC T1 systems are separate from the pack. Sun Fire UltraSPARC T1 much, much less expensive to run than is competitors. How about those Cool Threads!
Here's the details on the configurations compared above:
How about scalability? Here's a good example of how the Sun Fire T2000 and the UltraSPARC T1 processor scales from 1 to 32 threads. Each SPECjbb2005 is a new thread. Throughput steadily increases as new threads are added, peaking at 32.
